This thesis focuses on a comparison of theory and concept of the injunctive relief in Thailand and other countries,aiming to analyse a proper method to rectify Thai ligislation on pre-litigation of injunctive relief in tort cases. This study found that the pre-litigaiton of injunctive relief of Consumer Case Procedural Act,B.E.2551 is the most suitable model of injunctive relief for applying in tort cases because it can be analogous to the Civil Procedure Code section 254(2).Moreover, this model resembies the injunctive relief system in the UK. Therefore, if this kind of pre-litigation of injunctive relief is applied, it will point the pre-litigation of injunctive relief in Thai legislation to the same direction with foreign laws and increase the efficiency the efficiency of Thai injunctive relief system.
